Fixed ball bearing hinge _ Which is the most professional? Hengshui Hao-_ damping fixed ball bearing hinge is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call the contact phone or pictures on this page, For the latest information, contact: Liu. Room for PTFE plate material used in ball bearing hinge friction coefficient test itself, as well as the materials used in triple-layer composite board combining fastness and compression test has been done in the material description is not repeated here. Ball bearing hinge plane and curved support plate bearing combination, completed horizontal movement to achieve the rotation plane and curved section features a ball joint mount fixed ball bearing slide hinge flat portion of the support plate when the spherical bearing, if the Such a spherical bearing surface formed part becomes full-rotation type of bearing, spherical bearing in the country called; and as the cylindrical surface becomes a one-way type support. Usually referred to swing column bearing, ball joint holder of such smaller radius of curvature of the surface if it is made, you can get a large amount of rotation, this seat features horizontal movement and rotational functions depend on the support plate Materials in contact with the sliding friction coefficient size. So, the ball bearing hinge dust and protective measures must be taken to prevent increased wear and friction coefficient. Another elastic fixed ball bearing hinge, if high strength brass support plate, since the contact surface machining accuracy is difficult to control and yearly aging, friction characteristics vary leaving the mobile device is rotated problem exists impaired function, so in addition to the use of the attention, but is also necessary to limit the large amount of rotation. Ball bearing hinges are developed on the basis on the basis of the pot bearing initiated on a ball joint mount, back in the 1970s, it developed into a foreign spherical seat, in 1988 China has also started to develop a spherical support seat and started for engineering practice, complete the national standard setting work in 2000, the spherical bearing not only involve adapt the scope of the corner and carrying capacity than ball joints are bearing large, so, enter the 1990s, spherical bearings China's large-span bridges in the project has been more widely used, and completed in 2008 a national standard revision work, while damping fixed ball joint bearing, completed the design of the core standard package involves drawing. General construction spherical bearing, ball bearing hinge by the bearing plate, spherical steel liner plate, the ball bearing slide hinge plane Teflon skateboards, skateboard spherical PTFE, seals and dust cover, etc. parts do, whose main components constructed spherical seat role and requirements. Ball bearing hinge plate can also be called a bottom basin, usually made of steel castings seismic fixed ball joint bearing, bearing small tonnage is also useful in the case of thick steel plate processing, mainly from the lower bearing plate fixed spherical PTFE plate of the role and support reaction force is transmitted to disperse or bridge piers supporting the platform. Ball bearing hinge rotates by sliding spherical steel liner plate between the spherical PTFE plate to achieve, but usually spherical steel liner plate steel castings finishing, ball bearings and spherical hinge processing completed Now there are cases using coated stainless steel surfaces. If after using steel processing, machining precision sphere will refer directly affect the function of bearing rotation, which points to attract attention.
